The period boob tenderness is undoubtedly a total pain, but it does mean your hormones are working particularly efficiently.
The pain is all down to the hormone party going on in your breasts. Our boobs have oestrogen and progesterone receptors meaning the hormone changes are super easily picked up. Thanks hormones, we’ll cope with the monthly swelling, congestion, tenderness and (for some ladies) lumpy breasts, and find a small amount of comfort in the fact that, yes, our hormones are working on top form.
